It's happening: Lou Dobbs' dream come true and Silicon Valley's worst nightmare. We're already seeing the reverse brain drain as smart immigrants take their U.S. educations and experience building companies and creating technology back to their home countries.

Many migrants awaiting asylum hearings in the U.S. never show up for their court dates. And the longer they stay in the U.S., the more sympathy they draw in the media and from many compassionate Americans.

Immigrants provide skills that we simply cannot afford to do without. They have contributed hugely to Britain's success.

My foundation now has some 120 football pitches laid out for children, a lot of them immigrants. We live in a multicultural society.

The U.K. needs a system for family migration underpinned by three simple principles. One: that those who come here should do so on the basis of a genuine relationship. Two: that migrants should be able to pay their way. And three: that they are able to integrate into British society.

In the poetry of immigrants, nostalgia is as common as confetti at parades or platitudes at political conventions.

We are a country of immigrants who have built this great nation, but it is legal immigration that we should be recognizing and encouraging.

Authorities that erect major obstacles to migration - or place severe restrictions on migrants' work opportunities - inflict needless economic self-harm, as they impose barriers to having their labor needs met in an orderly, legal fashion. Worse still, they unintentionally encourage illegal migration.

Legal immigrants deserve respect for following the laws of our nation and completing the process. This is not an extreme concept. It is a matter of simply protecting our nation's sovereignty and knowing who is coming into our nation.

Many of the concessions that leading Democrats seem willing to make - from cutting diversity visas to chipping away at family visas - would be made on the backs of black immigrants, people from Africa and the Caribbean who deserve these policies to remain intact as some of the few legal tools they have to immigrate to this country.

Legal immigrants have been an engine of economic growth, innovation, and entrepreneurship on this continent for longer than we have been a nation.

In order to create real, long-lasting reform, we must create a pathway to legal status for the millions of undocumented immigrants who have made lives for themselves and their families in the United States.

Every lethal terrorist attack in the United States since 9/11 has been carried out by an American citizen or a legal permanent resident, not by recent immigrants or by refugees. So tamping down immigration won't fix the real issue, which is 'homegrown' terrorism.

There are a lot of Latinos who believe that allowing illegal immigrants to cut in front of the line ahead of those pursuing the legal path sends the wrong signal. The GOP needs to articulate that message respectfully but boldly.

I do believe that people hire immigrants, legal and illegal immigrants, to do certain jobs that maybe possibly could go to American citizens, and that's unfortunate. If they're here legally, I think it's OK. If they're here illegally, then they ought not be taking jobs from American citizens.

The reality is for 50 years in this country, federal law has required people that are illegal - or that are immigrants - or that are legal immigrants to this country to carry documentation to that effect. And that has been the law for 50 years.

I love immigrants. Legal, illegal - they're not to be despised.

As legal residents, immigrants would contribute more in taxes, spend more at our businesses, start companies of their own and create more jobs. Immigration is not a problem for us to solve but an opportunity for America to seize.

I'm for the DREAM Act. It makes so much sense. Following the implementation of the DREAM Act, we'll have a case study we can point to where we can say that we provided a path to citizenship or legal involvement in the community for these young immigrants, and the sky didn't fall.

The factual reality is that the vast majority of immigrants - legal and illegal - contribute more to this country than they take out in social services.

I love the new legal immigrants; they want their kids to be safe just like I do.

Therefore, if we are a Nation of laws and a Nation of immigrants, immigration should occur within a legal framework, not through the machinations of illegal schemes and scams that threaten our national security.

I have written about the dispossessed, immigrants, the condition of women who do not enjoy the same legal rights as men, the Palestinians who are deprived of their land and condemned to exile.

Instead, California is one of only 10 states that provides in-state college and university tuition to illegal immigrants. That's grossly unfair to a legal high school student who moves out of California for a year, then returns to attend college.
